BACKGROUND OF THE INVENTION

1. Field of the Invention

Methods and apparatuses consistent with the present invention relate to directly writing multimedia data onto a digital device, and more particularly, to converting multimedia data written in a storage medium to a format playable in a digital device using only one operation, and copying or moving the multimedia data to a folder for digital device at the same time.

2. Description of the Related Art

Because there are more and more kinds of digital devices and because of increased contact of users with digital devices, it has become important to provide a better user interface. Generally, it is necessary to interface with a personal computer (PC) in order to write multimedia data onto a digital device. It is possible to write multimedia data only when multimedia data stored in the PC is copied or moved to a digital device via a connection medium such as a Universal Serial Bus (USB). To write audio data stored in an audio compact disc (CD) onto a digital device, multiple steps are necessary. The audio data must be converted to data that employs a format writable on the digital device (e.g., MPEG-1 Audio Layer 3 (MP3) or Windows Media Audio (WMA)), and be stored in the PC. Then, the audio data must be written onto the digital device by a user's manipulation of a user interface. Writing the data stored in an audio CD onto a digital device will be described in reference to FIG. 1.

FIG. 1 illustrates writing contents stored in an audio CD onto a digital device according to a related art.

After inserting an audio CD that stores audio data into PC (S12), a user selects a track to be converted by executing a converting program such as a ripping program, and then sets an option such as setting a bitrate, selecting a storage directory, or determining whether to use a CD database (CDDB) server (S14). The selected track in the audio CD is converted to a playable format (e.g., MP3 or WMA format) for use on a digital device by using the converting program, and then is stored in a storage directory of a local PC (S16). A user connects the digital device to a PC by using an USB, and selects a data file to be written on the digital device connected with the PC by executing a searching program (S18). The selected file is written onto the digital device by dragging and dropping it (S20).

However, it is inconvenient for a user because several steps are needed to write audio CD data onto a digital device. For example, a user has to select several options (e.g., selecting a storage directory, setting a bitrate, determining whether to use a CDDB server) in ripping the audio CD. Moreover, if the user does not remember the directory of the PC where the ripped file is stored, the user must search each directory for the file in order to locate and move the data onto a digital device. That is, moving data in a digital device consists of several steps, making it inconvenient for a user.

FIG. 2 illustrates an apparatus for writing multimedia data on a digital device according to an exemplary embodiment of the present invention.

An apparatus 100 illustrated in FIG. 2 comprises a sense unit 110, a display unit 120, a converting and writing unit 130, an information receiving unit 140, and an input unit 150. A content database (DB) server 200 transmits and receives information with the information receiving unit 140. A digital device 300 is connected to the apparatus 100 by USB, or other such connection method.

The digital device 300 may be a cellular phone, a camera, a personal digital assistant, or other such device.

The sense unit 110 senses multimedia written on a storage medium. If a user selects the track, and locates it in the MP3 player by dragging and dropping it in order to move a track of an audio CD to a MP3 player, the sense unit 110 recognizes the track to write in the digital device 300, and drives the information receiving unit 140, which will be described later.

The display unit 120 displays a user interface screen where multimedia data and a folder for the digital device 300 to write the multimedia data is displayed by receiving information on progressing status in present via a converting and writing unit 130.

The input unit 150 receives a movement command to write multimedia data in a folder for the digital device 300. It is desirable that the order is executed by dragging and dropping with a mouse.

The converting and writing unit 130 writes the multimedia data in the folder for the digital device, and converts the multimedia data to be playable in the digital device at the same time.

The information receiving unit 140 searches a content DB server 200 where multimedia metadata is being stored for the corresponding multimedia metadata, and receives it when multimedia data is sensed via the sense unit 110 by inserting a storage medium such as an audio CD into a PC. Specifically, the information receiving unit 140 determines whether multimedia data corresponding to the track is in the content DB server by transmitting information on the track received from the sense unit 110. As the result, if multimedia data corresponding to the track is in the content DB server 200, the information receiving unit 140 receives the multimedia metadata, and forwards it to the converting and writing unit 130, which will be described later.

The converting and writing unit 130 writes the multimedia data in the folder for the digital device 300, and converts the multimedia data to be playable in the digital device by using multimedia metadata received from the information receiving unit 140 at the same time. The converting and writing unit 130 also writes tag information (e.g., ID3Tag V1, ID3Tag V2) about multimedia data converted to be playable in the digital device 300 in a folder for the digital device 300 together.

In the present invention, the storage medium refers to hard disk drive, audios, videos, CD, digital versatile disc (DVD), web hard, transportable storage medium, content server to provide multimedia data via wire and wireless network, and a medium where multimedia data, which has yet been converted to be playable in the digital device, is stored. Accordingly, the present inventive concept is applied not only when content stored in a CD is written on the digital device 300 but also when a multimedia file is directly downloaded to the digital device 300 via Internet.

An exemplary method for directly writing multimedia data on a digital device will be described with reference to FIGS. 3, 4 and 5.

FIG. 3 is a flowchart showing a method for directly writing multimedia data on a digital device according to an exemplary embodiment of the present invention. FIG. 4 illustrates displaying a user UI screen to display multimedia data and a folder for a digital device according to an exemplary embodiment of the present invention. FIG. 5 illustrates showing a user UI screen to display that multimedia data is converted to be playable in a digital device, and is written in a folder for a digital device according to an exemplary embodiment of the present invention.

The sense unit 110 operates the information receiving unit 140 after sensing multimedia data written on the storage medium (S102). After connecting to the content DB server 200 (S104), the information receiving unit 140 receives track information on the storage medium, and then transmits it to the content DB server 200 (S106). Then the information receiving unit 140 determines whether the multimedia data corresponding to the track is in the content DB server 200 (S108).

If the multimedia data corresponding to the track is in the content DB server 200, the information receiving unit 140 will receive the multimedia metadata (S110). If the multimedia data is not in the content DB server 200, another track is received at operation S106. Then the information receiving unit 140 transmits the received multimedia metadata to the converting and writing unit 130 (S112).

The display unit 120 displays a user screen to display the multimedia data and a folder for the digital device 300 to write the multimedia data (S114). The user interface screen will be displayed after the sense unit 110 senses multimedia is written on a storage medium. If the digital device 300 is connected with the apparatus 100 via wire or wireless, the corresponding folder is displayed on the left side of FIG. 4. As an exemplary embodiment of the present invention, a screen that displays writing contents stored in an audio CD in a MP3 player is illustrated. Referring the left side of FIG. 4, folders such as “my MP# player”, “my PC”, “music store”, and “my audio-CD” are displayed on a directory as “music library”. Audio file information in “my audio-CD” is displayed on the right side of FIG. 4. In displaying the information, the information receiving unit 140 transmits track information of the audio CD received by the sense unit 110 after connecting to the content DB server 200, at this time, if the multimedia data that has track information on the audio CD is in the content DB server, the information receiving unit 140 will receive the multimedia metadata. Then the display unit 120 displays the received information.

A user inputs a movement command to the input unit 150 to write the multimedia data file shown at the left side of FIG. 4 in a folder for the digital device (S116). That is, dragging and dropping are operated to write the file displayed at right side of FIG. 4 in the folder for the digital device. Writing refers to copying and moving a multimedia data file.

In converting the sensed multimedia data to be playable in the digital device 300 and writing it in a folder for the digital device 300 as a last step, desirably, the converting and writing unit 130 converts the multimedia data to be playable in the digital device 300 by using multimedia metadata received from the information receiving unit 140, and writes the multimedia data in the folder for the digital device 300 at the same time (S118). At this time, tag information according to a format (e.g., MP3 or WMA) for multimedia data able to be played in a digital device is also written in the folder for the digital device 300.

When an audio file dragged and dropped by a user is written in “my MP3 player” folder, it is converted to a MP3 format file playable in a MP3 player, and is written in “my MP3 player” folder. Referring FIG. 5, converting a music file “A singer-a title” among the content files stored in an audio CD to a MP3 file is shown at center window of the screen of FIG. 5. Especially, a ripping program refers to converting digital sound data to a file able to be processed in a computer, i.e., the program abstracts the digital sound data written on a music CD, converts the data to the file able to be processed in a computer, and then saves the data. At this time, a tool for abstracting and converting data refers to ripping software, ripping tools, or rippers.

The storage medium refers to a hard disk drive, audios, videos, CD, DVD, web hard, transportable storage medium, content server to provide multimedia data via wire and wireless network, or a medium where multimedia data, which has yet been converted to be playable in the digital device, is stored.

It is to be understood that the scope and spirit of the present invention also includes a writing medium to write a machine-readable program necessary for carrying out the method for directly writing multimedia data on a digital device described in the above exemplary embodiments of the present invention.

According to the present invention, it is possible for a user to write a multimedia file on a digital device by one operation, without having to set options when the multimedia file is converted to a format playable in a digital device.

According to the present invention, operation may be simple because if a file is downloaded to a PC after user's authentication when downloading a digital file via Internet, a file may be converted and written on a digital device at the same time.
